HIGH-FREQUENCY CUTOFF IN TYPE III BURSTS
In this article we report about a group of solar bursts with high-frequency cutoff, observed on 19 August of 2012 near 8:23 UT, simultaneously by three different radio telescopes: the Ukrainian decameter radio telescope (8-33 MHz), the French Nançay ...

Schumann Resonance Frequency Increase Following Recurrent Solar Wind Stream Onsets
Abstract Recurrent high‐speed streams and corotating interaction regions (HSS/CIRs) are common solar‐wind drivers, but their influence on Schumann resonance (SR) frequencies remains poorly quantified. We analyzed 173 threshold‐defined HSS/CIR proxy onsets using superposed epoch composites, bootstrap uncertainty, and a month‐matched random‐epoch null ...

Abstract This study examines the equatorial ionospheric response over the South American sector during the onset of the extreme 2024 Mother's Day geomagnetic storm, which began at ∼17 UT on 10 May and reached the G5 level. Pronounced disturbances in ionospheric electrodynamics were observed under both daytime and nighttime conditions. Variations in the

The Association of Solar Radio Bursts of Spectral Type III with Chromospheric Flares
The relationship of radio bursts of spectral type III to solar flares is investigated by comparing simultaneous optical and radio observations. Over 300 flares are examined, 85 per cent. of which are microflares (class 1?). About 20 per cent.
